Crawling GCC Government Documents: What Blocked Me

Building GCC LexAI meant ingesting AI regulation documents from UAE and Saudi Arabia government websites. The tech stack worked fine. The websites did not always cooperate.

Saudi .gov.sa blocks non-Saudi traffic entirely

This took me a while to accept as the actual explanation.

cst.gov.sa, cma.gov.sa, sdaia.gov.sa, and their subdomains return connection timeouts. Not 403s, not redirects — timeouts. I tried from Japan, Malaysia, and the US. Same result every time. The problem isn't the origin country; it's that Saudi government sites appear to block all non-Saudi IP ranges at the network level.

Changing your crawler's location doesn't help. Proxies in GCC countries are the theoretical fix, but the practical one is to not depend on primary government URLs at all.

What worked: Some agencies publish via CDN subdomains (cdn.nca.gov.sa), which resolve from outside Saudi Arabia. For agencies without CDN mirrors, I used documents hosted by OECD, law firms, and academic institutions — the same PDFs, just not from the primary .gov.sa domain.

sca.gov.ae returns HTML where you expect a PDF

The Securities and Commodities Authority's PDF URLs respond with Content-Type: text/html and serve a webpage. Not a redirect, not an error — a 200 response with HTML content at what looks like a PDF path.

Detection fix: check the first four bytes of the response body for %PDF. If the content-type says PDF but the bytes don't, discard it and find another source. VARA (the virtual assets regulator) hosts its rulebooks on a CDN with clean, stable URLs — that became the fallback for SCA content.

Lessons

Don't rely on official URLs as your primary source for government documents. .gov domains optimize for human browsers, not automated access. CDN mirrors and secondary hosts are often more reliable for programmatic use.

Treat PDF availability as data you need to verify. A URL that returns 200 isn't necessarily a PDF. A PDF URL that works today may return HTML tomorrow. Build verification into the ingestion pipeline, not as an afterthought.

Geo-blocking is a real constraint in the GCC. UAE government sites were accessible. Saudi ones were not. Design your data sources with this asymmetry in mind if you're building anything cross-GCC.
